Devil's Claw / Unicorn Plant (Proboscidea louisianica) is a rugged, low growing shrub in the Martyniaceae family. It is predominantly grown for its mature seed pods, which are hooked and used for basket weaving. However, the plant is also edible! Immature pods can be cooked like okra, and mature seeds can be shelled and eaten like sunflower seeds.
Edibility is definitely an acquired taste. As the plants grow, all parts exude an oily resin, which is acrid smelling and traps bugs. This is considered a carnivorous plant to some. I personally enjoyed eating the pods, because we had a large okra crop failure the same year and I was excited to try something similar. Definitely not as gooey or mushy as okra though.
